Laboratory Grown diamonds, also known as synthetic diamonds, are man-made stones. 
This is achieved using the High Pressure High Temperature (HPHT) or Chemical Vapor Disposition (CVD) method.
The factory made synthetic diamonds are mostly produced in China and India.
IGL's LAB GROWN DIAMOND grading reports provide the same information as the IGL Diamond Report.
However, the title of the certificate is clearly stated as "LABORATORY GROWN DIAMOND” and the color of the certificate is green to ensure that buyers and sellers can clearly see and understand that this is a synthetic diamond.
